In what way will JS Park be utilized in the CL final? Some have said that Park will be assigned to shadow Messi, but wouldn't that be playing out of position for Park?
If Park indeed plays in the final. I think if you stop Iniesta and Xavi, no mean feat I know, you stop Messi, and Villa.
Fortunately Messi and Villa aren't in great form. But I agree with you Ian - Xavi and Iniesta pull the strings for Barca, and putting pressure on them will be key.
